What year is my evinrude 175 ?

[THEFERMANATOR]

Most of the earlier engines prior to the 90's would have a welch plug somewhere in the block that would also have the model info on it. If not, put a few pics up and we can give you an idea of what year range it falls into. Most parts besides carbs and ignition fit a wide range of engines(one of the reasons people can still get parts for the EVINRUDE/JOHNSON engines is MANY parts can fit engines from over 10 years). Things like jetting and igntion can be year specific though.
